Structured data
Structured data does not make a model cite you. It removes reasons not to.
Product, in JSON-LDschema.org
"@type": "Product",
"name": "Seolwha Daily Sun Fluid SPF50+",
"brand": { "@type": "Brand", "name": "Seolwha" },
"additionalProperty": [
{ "name": "SPF", "value": "50+" },
{ "name": "PA rating", "value": "PA++++" }
]The useful types for a consumer brand are narrow: Organization with sameAs links to establish who you are, Product with real specification values, Article with a named author for editorial content, FAQPage where genuine questions and answers appear on the page, and BreadcrumbList for context.
Two rules matter more than coverage. First, never mark up content that is not visibly on the page — it violates the search engines’ own structured-data policies, whatever a syntax validator says. Second, use stable @id values so the same entity referenced from different pages resolves to one node rather than several near-duplicates.
